- Abstract
Introduction: Knowing the morphology of the pulp chamber and root canals, as well as their diversity, is key to endodontic treatment success. Mandibular molars are a group of teeth with complex internal anatomy of which knowledge is paramount. Objective: The objective of this study was to assess, by means of four methods (radio-graphic, macroscopic, microscopic and anatomical), the amount and configuration of root canals present in man-dibular first molars. Methods: This was a cross-sectional ex vivo, observational and descriptive study conducted with 50 permanent mandibular first molars. The following exclusion criteria were applied: teeth with completely destroyed crowns, incomplete root formation, resorption and/or perforation, including healthy and semi-healthy crowns. Results: A total of 24% mandibular first molars had three root canals, with a cross-section flattened mesiodistally and elongated buccolingually to the full extent of mesial (48.6%) and distal canals (52.2%) being the most prevalent. However, other possible configurations, such as circular morphology both in mesial (46.6%) and distal canals (38.1%), and cases of five root canals (16%) could also be seen. Conclusion: The methods adopted allowed us to find that, in mandibular first molars, there was a prevalence of root canals flattened mesiolingually and elongated buccolingually. Three root canals were prevalent; however, variations may occur.
